3SFTE project Options

[digs]

Hi guys, don't post on here really as post on a UK celica forum.... but thought I would share what I have done to my SSI.

Following the various 5sfte posts and guidance, I have now turbo'd my 3sfe engine, some pics of the engine bay (its had a little more done since this one - including changing boost gauge t-off point to the map sensor line) and other bits at end of post.

Have installed;

3sge injectors
ct26 turbo
emanage blue (getting tuned in a couple of weeks)
ST185 manifold
ST185 map sensor
2.25" intercooler pipes and intercooler
Apexi BOV
ST185 pan
boost and oil gauges
2.5" custom ss exhaust

Been a fun and frustrating build, the turbo would not clear the coolant hard lines on the rev 3 3sfe, so I had to source a spacer for between the manifold and turbo. Changing the oil pan is fun too! Didn't need to relocate oil filter, so that was a bit easier. Coolant lines off the throttle body so again pretty easy.

Intercooler piping was interesting, right side through air pox route, left side was a bit of a squueze! But did not need ot remove a/c or anything else.

Not driven it on boost yet, but has been driven for several hours off boost, and doesn't miss a beat. Injector size has gone from 215cc (rev 3 3sfe stock I believe) to 295 (3sge stock), running on stock fuel pump, so some scope to improve there.

First map though is just a safe one to ensure no det, etc. Plans next will be;

wideband sensor and gauge (hooked into emanate)
prob bigger injectors and fuel pump
sort out second output for boost gauge from throttle bottle to leave map sensor feed unmolested
Wilwood 4 pot brakes

looking forward to running boost!

Thanks for the info...

Tuning: Once the full throttle on-boost tuning is sorted, the low-load regions can be fine tuned. Resulting in better driveability and mileage and better turbo response.


Tuning is ultra safe at mo, fuelling no issue (over if not less) and ignition pulled for safety, so there are areas of moving back there.

Exhaust after turbine: This will greatly effect the response of the turbine. The turbine would achieve maximum response and efficiency with the downpipe and all exhaust removed completely. A restrictive enough exhaust will actually reduce the amount of boost your turbo can make in total, with a corresponding hit to response!

Have 2.5" exhaust with sports cat, so don't think it would be that....

Turbo center section: The turbocharger's bearing. This should be in good condition before judging the response of the turbo. Otherwise it's like judging a restaurant by tasting a week-old doggybag from the fridge.


THIS^^ Second hand ct26 thrown on, doesn't smoke but providence unknown.... may well be crappy and that's the reason, thinking of reconing or going for a replica to see.


Charge piping and intercooler: Generally, yes the compressor will fill up any arrangement of pipes, couplers, bends and cooler core. But these volumes can be optimized for the sake of turbo response

Clocking the turbo would give me a better route
